[An on-line version of this announcement will be available at http://www.postfix.org/announcements/postfix-2.7.0.html]
Postfix stable release 2.7.0 is available. For the past several releases, the focus has moved towards improving the code and documentation, and updating the system for changing environments. - Improved before-queue content filter performance. With "smtpd_proxy_options = speed_adjust", the Postfix SMTP server receives the entire message before it connects to a before-queue content filter. Typically, this allows Postfix to handle the same mail load with fewer content filter processes. - Improved address verification performance. The verify database is now persistent by default, and it is automatically cleaned periodically, Under overload conditions, the Postfix SMTP server no longer waits up to 6 seconds for an address probe to complete. - Support for reputation management based on the local SMTP client IP address. This is typically implemented with "FILTER transportname:" actions in access maps or header/body checks, and mail delivery transports in master.cf with unique smtp_bind_address values. - The postscreen daemon (a zombie-blocker in front of Postfix) is still too rough for a stable release, and will be made "mature" in the Postfix 2.8 development cycle (however you can use Postfix 2.7 with the Postfix 2.8 postscreen and dnsblog executables and master.cf configuration; this code has already proven itself). No functionality has been removed, but it is a good idea to review the RELEASE_NOTES file for the usual minor incompatibilities or limitations. You can find Postfix version 2.7.0 at the mirrors listed at http://www.postfix.org/ The same code is also available as Postfix snapshot 2.8-20100213. Updated versions of Postfix version 2.6, 2.5 and perhaps earlier will be released with the same fixes that were already included with Postfix versions 2.7 and 2.8. Wietse
